Case Type   : 事件触发器
Case Name   : 【事件触发器】修改事件触发器名称，新名称不存在且合法，修改成功
Create At   :   2024/07/15
Owner       :   sungang14
Description :
    预置条件：
        1.创建事件触发器函数：
        CREATE OR REPLACE FUNCTION f_eventtrigger_0052()
        RETURNS event_trigger
        LANGUAGE plpgsql
        AS $$ BEGIN
        RAISE NOTICE 'test_event_trigger: % %', tg_event, tg_tag;
        END;
        $$;
        2。创建事件触发器
        CREATE EVENT TRIGGER eventtri_eventtrigger_0052 ON ddl_command_start EXECUTE PROCEDURE f_eventtrigger_0052();
    测试步骤：
        1、修改事件触发器名称
        ALTER EVENT TRIGGER eventtri_eventtrigger_0052 RENAME TO eventtri_eventtrigger_0052_new;
        2、查询系统表pg_event_trigger确认修改成功
        SELECT * FROM pg_event_trigger WHERE evtname = 'eventtri_eventtrigger_0052_new';
Expect      : 
        1、修改成功
        2、系统表中名称已修改
